Abstract (en)
The present invention relates to a system for de-warping images of an applicable surface, including applicable curled surfaces, and in particular of images of curled documents (30). The system (1) includes a processor (25) linked to an image capture means (2) which: captures an image of the surface (30), said image having a warp corresponding to the non-planar surface; generates from the image a first set of data points representing the three-dimensional profile of the non-planar surface relative (30) to a planar reference surface (12); fits to the first set of data points a second set of data points representative of an applicable mesh; and uses the second set of data points to texture-map the image (12) in order to de-warp the image. <IMAGE>
